Smaller than many conventional automobile broadcast band recei-
vers, the sophisticated IC-28A/E transceiver provides 25 watts of
output power on any frequency in the 2 meter band and contains an
internal speaker as well.
Front panel layout is extremely simple in spite of the great number
of functions available. The total number of controls on the front
panel is significantly fewer than other models currently available
while, at the same time, new features have been added resulting in a
mobile unit that is safe and easy to use while driving without sacri-
ficing performance.
The LCD front panel readout features a particularly wide viewing
angle designed to enable the driver to easily see the display, even in
bright daylight, without changing position.
Variations in ambient light conditions pose no problems when using
the IC-28A/E since the built-in light sensor automatically adjusts a
dimmer circuit to control the backlighting of the display to suit the
time of day or night that you are operating. This feature is
particularly convenient for night operation to reduce eye fatigue
caused by overly bright displays.
The IC-28A/E introduces a large capacity memory with 21 fully
programmable memory channels. These memory channels place a
variety of communications functions at the fingertips of the driver.
e FREQUENCY SCAN:
The entire band is searched continuously with frequency incre-
ments specified by the operator.
eMEMORY SCAN:
All memory channels are continuously checked.
With 38 different subaudible tones standard on the IC-28A (U.S.A.
version), maximum communications coverage is assured by allowing
full access to all your local repeaters.
Two new optional units specially designed for the IC-28A/E are ideal
for handling the crowded band conditions found on 2 meters in
many locations. Either the UT-28 or the UT-29 may be installed.
eUT-28 DIGITAL CODE SOUELCH UNIT:
Incorporating a system of digital coding and decoding, the UT-28
option allows a "personalized" squelch to be programmed using 1
of 100,000 different code numbers.
e UT-29 TONE SQUELCH UNIT:
The UT-29 is a subaudible tone encoder/decoder which may be
installed as an alternative to the UT-28 Digital Code Squelch Unit.
